5MW <strong>and</strong> 45MW in both the Low Voltage <strong>and</strong> Medium Voltage versions. It is<br />
effective also in vessels with operating profiles that require variable speeds, such<br />
as OSVs.<br />

Wärtsilä Low Loss Hybrid (LLH)<br />
The introduction of Wärtsilä Low Loss Hybrid (LLH) <strong>and</strong> its integration with a conventional<br />
diesel or dual-fuel engine generating sets, offers significant efficiency<br />
improvement by running the engines on optimal load <strong>and</strong> absorbing many of the<br />
load fluctuations through batteries. The system is designed <strong>and</strong> integrated to optimise<br />
the overall operation of the vessel.<br />
The power <strong>and</strong> energy capacity of the battery should be suitable to allow the engine<br />
to run for most of the time on optimal loads. The system is designed <strong>and</strong> integrated to<br />
optimise the overall operation of the vessel. A key element is hybrid control algorithms<br />
for load sharing between units <strong>and</strong> efficient power <strong>and</strong> energy management.<br />
